Specification of Letters Patent.

Patented Sept. '7, 1915.

. Application filed May 14, 1914. Serial N 0. 838,437.

To all whom it may concern: I

-Be it known that I, JOSEPH F. JoNEs, Jr., a-citizen of the UnitedStates, residing at Bakersfield, in the county of Kern and State ofCalifornia, have invented new and useful Improvements in Pumps, of whichthe following is a specification.

This invention relates to a compressed air lift system for pumpingWater. or oil, or

water and oil with solids in suspension, from Wells, sumps, pits, etc.

It is one of the objects of the present invention to provide a simple,practical air lift pump with a novel form of air lift mechanism by whichthe air is discharged into the flow pipe at a plurality of points toeffec tively lift a column of liquid; and also to provide means by whicha spiral or rifiing motion is imparted to the ascending water and air.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure 1 is a verticalcentral section of the well, showing the application of the invention.Fig. 2 is a plan view of the nozzle proper. Fig. 3,is a vertical centralsection on the line w-w, Fig. 2. Fig. 4-is an end view of the nozzle.

Referring'to the drawings, A indicates the casing of a well and 2 thesurface frame from which the flow or discharge pipe 3 is hung. Extendingdown through the flow pipe to within a short distance of the lower endof same is an air pipe 4, and secured on the end of said pipe is adischarge nozzle casing 5. The upper end of the flow pipe is providedwith a T-fitting, as at 6, through one side of which the water ispermitted to discharge, and the upper end of said fitting is providedwith a plug 7 in which the air pipe is secured.

The air discharge nozzle proper, which is more clearly shown in Figs. 2,3 and 4, includes an inverted T-shaped casing 5. to which the lower endof the air pipe is connected, as at 8. Positioned on opposite sides ofthe air pipe 4, and eccentric to pipe 3, are nozzles 9 and 10 connectedwith an interior air passage 11 in casing 5 and communicating with asuitable source of air supply under pressure through the pipe 4.

The discharge opening 12 in each nozzle is preferably tapered to givethe discharging air a greater velocity. If desired, the nozzles 9- 10may be given an opposite tilt to throw their axes, out of parallelismwith the axis of the flow pipe in order to impart a uniform swirling orspiral motion to the column of liquid moved by the device.

In operation, the pressure in the air pipe must be greater than thehydrostatic pres sure of the water at the bottom of the pipe and nquantities sufficient to make the ascendmg column of air and water inthe flow plpe lighter in its total height than the we1ght of an equalcolumn of solid Water of the depth of the well from the surface of theWater to the bottom of the pipe. The air discharging through theangularly posit oned eccentric nozzles imparts a spiral motion to thewater and also causes the air to become evenly distributed, therebyhelping or increasing the lifting efficiency within the flow pipe. Thevelocity created by the tapered openings in the nozzles is also takenadvantage of in this instance as it gives an impact to the water whichfurther aids the lifting efficiency. The spiral motion imparted by thedischarging air from the angularly positioned nozzles is of greatadvantage where more or less solid material, such as sand and grave], isliable to enter the flow pipe, as the spiral motion of the water keepsthe solid particles in constant agitation and motion which permits it tobe discharged with the ascending or outfiowing column of water.

An air lift designed as here shown is simple in construction and may beeasily applied to any standard form of well, as it is only necessary toprovide a surface frame by which the flow and air pipes may besuspended.

A suitable form of valve 14 may be pro vided for the purpose ofcontrolling the volume of air admitted to the well and a valve 15 may beprovided on the outlet pipe for the purpose of closing same when it isdesired to blow back or clear the lowerend or intake of the flow pipefrom obstructing materials.

The materials and finish of the several parts of the pump are such asthe experience and 'udgment of the manufacturer may dictate. ariouschanges in form, proportions and minor details of construction may beresorted to within the scope of the appended claim and I do not wish tolimit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure byLetters Patent is In a compressed air lift pump, the combination with anouter circular flow pipe, of an air pipe concentrically positionedtherein and extending to a point adjacent the lower end thereof toprovide an annular space between said flow pipe and said air pipe, aT-shaped casing secured on the lower end of said air pipe and having itsopposite ends closed, a discharge nozzle projecting at substantiallyright angles from said casing on diametrically opposite sides of saidair pipe substantially midway of said annular.

space, said nozzle being inclined to the vertical and dischargingupwardly to produce.
